ABSTRACT:
A road marker having a stiff but resilient body including a cavity formed therein to receive a suitable adhesive material for securing the marker to the road surface, and adaptable for the inclusion of one or more apertures in said body to receive one or more hermetically sealed lens and retro-reflector elements prior to adhesion of the road marker to the roadway. The body of the road marker is formed with a continuous edge portion and a frusto-conical central portion configured so as to limit contact between vehicle tires and the outer lens surface which may be disposed therein, thereby limiting abrasion and extending the useful life of the road marker. The body of the road marker also includes an aperture to receive a nail in order to facilitate installation of the road marker on the road surface.
